Possessing valuable operational properties, the vast majority of polymer composite materials (PCM) tend to ignite and spread the flame, the emergence of dangerous fire factors, leading to loss of life and property damage. The present article is concerned with influence of chemical nature and content of mineral fillers, phosphate plasticizers, bromine-containing fire-retardant agents, and dicyclopentadienyliron (ferrocene) derivatives on thermal fastness, flammability and smoke-generating ability of polymer composite materials. It’s shown that the main parameter defining the influence of mineral fillers on flammability of polymer composite materials is the specific amount of heat absorbed by fillers. It’s proved that bromine-containing fire-retardant agents increase smoke-generating ability of materials and allow obtaining low-flammable polymer composites with smoke-developed index not exceeding 500 m2/kg and high performance factors. The rational use of mineral fillers, bromine-containing fire-retardant agents, and ferrocene derivatives makes it possible to develop PCMs with reduced fire danger and high performance indicators.
